Title: Control system for collision of session setting
Inventor: YAMADA MITSUJI
IPC: H04L12/70
Filed: 1982-03-27
Abstract: PURPOSE:To eliminate effectively the collisions among session setting requests, by setting the priority to the session setting requests given froma logical unit and accepting the setting request of higher priority when a collision arises among the session setting requests. CONSTITUTION:Nodes A-F are set within a network, and a logical unit LU2 of the node A transmits a session setting request to a unit LU4 of the node B. In this case, the priority is set to the setting requests with allotment given to transmitter and receiver addresses. When a session setting request is received from the LU4 after a session setting request is transmitted, the LU2 and LU4 compare the priorities between the received and transmitted setting requests. Then the request of higher priority is received, and the request having a lower or equal priority is rejected. Thus a collision can be effectively eliminated among session setting requests for an equivalent and decentralized network without using any special hardware.

Title: Superconducting device and protective method of superconducting coil
Inventor: ASANO KATSUHIKO
IPC: H01F6/02
Filed: 1991-03-15
Abstract: PURPOSE:To promote the propagation of a normal conductive section by sealing an upper space by closing a remote control valve mounted to the upper section of a superconducting coil at the time of quenching, pushing down the level of liquid helium by vaporized helium gas and elevating the temperature of the superconducting coil. CONSTITUTION:When a superconducting coil 1 begins to be quenched, the quenching is detected, and a remote control valve 14 is closed instantaneously. Liquid helium gradually vaporizes by the heat generation of a normal conductive transfer section generated in the superconducting coil 1, but the level of liquid helium 16 is pushed up by the vaporized gas because the outlet of a flow path is closed by the remote control valve 14, and a gas space in a partition wall 5 is expanded. Consequently, the temperature of the superconducting coil 1 is elevated, and a normal conductive region is spread quickly. Accordingly, the propagation speed of the normal conductive transfer section at the time of quenching is increased, and the localization of the energy of the superconducting coil is prevented, thus improving safety.
